Module M10 - Participatory 3D Modelling

Unit M10U04 - Capturing Data from a 3D Model and Georeferencing them

Introduction

This Unit orients trainees about the process of extracting data from a three-dimensional (3D) model by using digital photography and preparing that data for import into a Geographic Information System (GIS) environment by georeferencing.

Data on a 3D model can be captured and transferred to a GIS. While transferring the data from one medium to the other, it is important to minimise data loss or erroneous georeferencing. Those who extract the data should be fully familiar with the attributes described in the map legend (i.e. the scale, symbols and associated descriptions).

Unit objectives / expected outcomes

After the completion of the Unit the trainee will be able to:

describe how to extract data from a 3D model using digital photography;
